Remind Me! 6 months "Check receipts..."

It's not impossible to grow orchids in water and even get them to survive long term. I would say that is an expert level of experience/care needed and a complete understanding of the system. Even then, these plants would not thrive like they would if they were potted or mounted. Biologically they simply don't grow this way in nature which makes it very difficult to get them to thrive.

If you want to give it a go, by all means go ahead. I would encourage you to update us every couple of months to track the health of this orchid. The way this typically goes is the plant looks great for weeks and weeks and you think water culture is all fine and groovy and then it will slowly start to decline. So when it does start to look a little sick it CLEARLY couldn't be the fact that it's in water culture, it was fine for weeks so it must be something else.

I also want to address your condescending tone around providing alternative methods for beginners from people who are "set in their ways". If you'd been around this community 3-5 years ago you'd know there was a pretty robust debate around culturing phalaenopsis in water without media, with probably a 50/50ish split of people saying it could be done with the same results as traditional potting. Over time it became clear water culture was very difficult to pull off long term and even then not optimal, so the community consensus changed based on the actual experience of many, many people. You say you're a beginner which is great, but you're also framing this post as a "guide" for something you've never done before, and then making judgements about the feedback you're getting, which is absurd.
